The double album Ten Years of Harmony contains material from the years 1970 to 1980, which was created during the time on the Brother Records label. The carefully put together compilation contains numerous hits by the band, but also some songs that have been seldom or completely unpublished to date. Ten Years of Harmony is an excellent overview of the second decade of the Beach Boys.
UHQCD stands for Ultimate High Quality Compact Disc and is a joint development of the Japanese CD replication company Memory-Tech and the Audio Quality CD Company from Hong Kong. Unlike conventional CDs, UHQCDs are not pressed from polycarbonate, but rather cast from a photopolymer and cured with UV light. Another layer of high-purity polycarbonate is applied to protect the softer photopolymer from scratching. The combination results in a significantly reduced reflection of the laser light inside the CD and an unmatched precise edge transition between pits and lands of the CD. UHQCDs are 100% compatible with normal CD players. Musically, the result is a sound that is strongly reminiscent of analog master tapes.
The discs offered by Universal Japan are also MQA (Master Quality Authenticated) encoded. Anyone who outputs the digital signal from the digital output of their CD player or the previously ripped data stream from their music server to a corresponding MQA-DA converter can generate a 24-bit signal with a sampling frequency of up to 352 kHz from the CD data.
